| Outline of Final Research Achievements |
Aiming at the development of 'biobetter' medicines that are improved in metabolic stability than the cytokine proteins which had been already approved as pharmaceutical molecules, we synthesized new cyclic protein in which the both ends of its polypeptide backbone are connected to each other with amide bond and analyzed its functional and structural characteristics. As a result, receptor binding activity of the cyclized cytokine and its cell proliferation activity were found to be equal to a wild type cytokine. Moreover, it has been demonstrated that the thermal stability and protease tolerance are superior to the wild type. This shows that the molecule are promising a lead compound in drug discovery for new biologics.
